It could if you actually maneuver your glasses to focus the light into a single spot like you would with a magnifying glass. I feel like you’ve never actually done it with a magnifying glass if you’re assuming it’s as simple as just getting it between the sun and the thing you’re trying to burn. It takes some fanagling to line everything up perfectly.

But also even without glasses (magnifying or otherwise), looking directly into the sun will fuck your eyes up.
